Synthesis of optical spring potentials in optomechanical systems

Description

We propose a method for tailoring the potential experienced by a moveable end mirror in a
cavity optomechanical system by specifying the spectral properties of the input field. We show
that by engineering the power spectral density of the cavity input field, a desired force function
can be approximated, with the accuracy of the approximation limited only by the linewidth of the
cavity. The very general technique presented here could have applications in many kinds of
optomechanical...[Show more] systems, particularly those used for sensing and metrology. We demonstrate the
method by applying it to improve the sensitivity of a particular gravity measurement.
